چکیده

The positive expression of MMP-2 and TIMP-2 were found in esophageal cancer (EC) tissue and correlated with cancer stage and clinico-pathological features of tumor and patients' survival. However, little is known about serum levels of those proteins in EC patients. The aim of the present study was to investigate the diagnostic significance of MMP-2 and TIMP-2 serum levels in EC patients in relation to clinico-pathological features of cancer. The study included 53 EC patients and 92 healthy controls. The serum levels of MMP-2, TIMP-2 and classical tumor markers CEA (carcinoembryonic antigen) and SCC (squamous cell carcinoma antigen) were assayed. The prognostic values and diagnostic criteria for the biomarkers tested were defined. Serum levels of MMP-2, TIMP-2 in EC patients were significantly lower, whereas CEA and SCC significantly higher than in control group. The diagnostic sensitivity of TIMP-2 (57%) was higher than those for other biomarkers tested and increased in combination with SCC (70%). Area under ROC curve for TIMP-2 (0.8698) was larger than for other proteins. In Cox's univariate analysis only SCC serum levels were significant prognostic factors for EC patients' survival. The results suggest the limited value of serum analyses of MMP-2 for tumor staging and prognosis in EC and the better usefulness of TIMP-2 than MMP-2 as a tumor marker in the diagnosis of EC, especially in combined use with SCC.

Expression of Matrix Metalloproteinase-2/9 and Tissue Inhibitor of Metalloproteinase-1/2 as Predictive Factors in Oropharyngeal Squamous Cell Carcinoma

Introduction: Metalloproteinases and their tissue inhibitors play an important role in the metastases formation. A multistage process of carcinogenesis requires the involvement of numerous enzymes and compounds that facilitate the expansion of tumor cells. The formation of metastases depends on both metalloproteinases and tissue inhibitors activation leading to the acti...

Evaluation of matrix metalloproteinases 1 and 13 in the patients with breast cancer and their association with the clinical features

Background: Metalloproteinase enzymes can lead to the digestion of the extracellular matrix and its compounds and ultimately facilitate the metastasis of cancer cells to other tissues. This study aimed to evaluate the activity of matrix metalloproteinases (MMPs) 1 and 13 in the tissue and plasma samples of the patients with breast cancer and their relationship with clinical features of the dise...
